Review comment:
The two handlers both need to capture _rpc_error(the member variable), I'm
afraid I can only change [&] to [this].
There's an alternate way to explicit capture, although I don't like this
style. How about this?
```
auto& rpc_error_ref=_rpc_error;
_add_batch_closure->addFailedHandler([&rpc_error_ref](){})
```
